Abstract

The invention discloses a magnetic resin wastewater purification device and method, and belongs to the field of sewage treatment. According to the magnetic resin wastewater purification device disclosed by the invention, the magnetic resin wastewater purification device is subjected to special structural design, so that on one hand, the anti-blocking performance of the device is improved by adopting a magnetic pore plate filtering and pulse gas inlet mode; on the other hand, the loss rate of the magnetic resin is reduced through the arrangement of the magnetic weir plate and the scraper. The magnetic resin wastewater purification device for wastewater treatment has the advantages of being anti-blocking, easy to operate, energy-saving, low in loss and the like, and is particularly suitable for wastewater treatment in industries such as lactic acid, papermaking, mining industry and power plants.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and more specifically relates to a magnetic resin wastewater purification device and method. Background technique [0002] Magnetic resin can quickly separate and remove pollutants in wastewater by efficiently adsorbing negatively charged humus, small molecule organic acids and other substances in sewage, and at the same time using its own magnetic effect to quickly settle. Magnetic resin purification technology has the advantages of cold resistance, high purification efficiency, fast reaction rate, and low operating cost. Magnetic resin purification devices are generally divided into two types: fixed bed and fluidized bed. Compared with fixed bed devices, fluidized bed devices occupy a smaller area and have higher processing efficiency. [0003] In the process of engineering application of magnetic resin purification technology, due to the small particle size of magnetic resin, on the one hand, ...
